Nahgir
Nahgir is a weirdo who acts nice to your face but will turn you into a villain behind your back. He’s the kind of person who will save your life just to get you to owe him.
He helped you pass the test, then said you were dumb for not getting it.
He gave you a gift, then told everyone you were cheap.
He protected you from the bullies, then said you were weak.
